But clearly this hasn't been enough for the proficient "Pacman," who has now added "dancing Gangnam Style" to his list of achievements.
As the Los Angeles Times notes, Pacquiao pulls off "some impressive "Gangnam Style" moves while training for his scheduled Dec. 8 fight against Juan Manuel Marquez" in this YouTube video (scroll to 1.10 to see the Pacman's fancy footwork).
"Pacquiao is set to face Marquez at the MGM Grand Garden Arena in Las Vegas," the newspaper notes.
This is not the only time the world champion boxer has been spotted grooving "Gangnam Style."
According to the Examiner.com, Pacquiao danced to the K-Pop viral hit on stage at the Universal Studios Amusement Park in Los Angeles earlier this month as part of his Filipino TV show "Manny Many Prizes:"
Pacquiao is the latest in a string of celebrities who have jumped on the "Gangnam Style" bandwagon.
The ultra-viral hit by Korean pop star Psy has already racked up more than 295 million views on YouTube since its release in July.
